Khet
Khet may refer to:
Heth
Ḥet or H̱et (also spelled Khet, Kheth, Chet, Cheth, Het, or Heth) is the eighth letter of the Semitic abjads, including Phoenician Ḥēt 
, Hebrew Ḥēt ח, Aramaic Ḥēth 
, Syriac Ḥēṯ ܚ, and Arabic Ḥā' ح.
Heth originally represented a voiceless fricative, either pharyngeal /ħ/, or velar /x/ (the two Proto-Semitic phonemes having merged in Canaanite). In Arabic, two corresponding letters were created for both phonemic sounds: unmodified ḥāʾ ح represents /ħ/, while ḫāʾ خ represents /x/.
The Phoenician letter gave rise to the Greek Eta Η, Etruscan 
, Latin H and Cyrillic И. While H is a consonant in the Latin alphabet, the Greek and Cyrillic equivalents represent vowel sounds.
Origins
The letter shape ultimately goes back to a hieroglyph for "courtyard",
(possibly named ḥasir in the Middle Bronze Age alphabets, while the name goes rather back to ḫayt, the name reconstructed for a letter derived from a hieroglyph for "thread",
. In Arabic "thread" is خيط xajtˤ or xeːtˤ
The corresponding South Arabian letters are 
ḥ and 
ḫ, corresponding to Ge'ez Ḥauṭ ሐ and Ḫarm ኀ.
List of districts of Bangkok
Bangkok is subdivided into 50 districts (khet เขต, also sometimes wrongly called amphoe อำเภอ as in the other provinces, derived from Pali khetta, cognate to Sanskrit kṣetra), which are further subdivided into 169 khwaeng แขวง, roughly equivalent to tambon ตำบล in the other provinces.
